can be read here.
External Interrupt Status.
If the GPIO0 is programmed to be external interrupt sources then the status
can be read here.
Interrupt Request Output on the SDO Pin.
nIRQ output is present on the SDO pin if this bit is set and the nSEL input is
inactive (high).
Direct I/O for GPIO2.
If the GPIO2 is configured to be a direct output then the value on the GPIO pin
can be set here. If the GPIO2 is configured to be a direct input then the value of
the pin can be read here.
Direct I/O for GPIO1.
If the GPIO1 is configured to be a direct output then the value on the GPIO pin
can be set here. If the GPIO1 is configured to be a direct input then the value of
the pin can be read here.
Direct I/O for GPIO0.
If the GPIO0 is configured to be a direct output then the value on the GPIO pin
can be set here. If the GPIO0 is configured to be a direct input then the value of
